These types were compared on selected, theoretically relevant measures of developmental antecedents and adult adaptation drawn from a careful review of each patient's clinical file. Although some differences among types emerged that corroborated expectations, other results directly disconfirmed speculations in the clinical literature. These results indicate that the variables comprising this taxonomic system tap important distinctions for this population, and when combined with the results of other studies, they provide an empirical base for revising and restructuring the system.
